Container for a spraying device

Abstract

Fluid liners and container assemblies for a spraying apparatus and related methods of use are provided. The disclosed liners include a side wall defining a fluid-containing portion and an open end, a flange extending outwardly from the side wall, and a latching member coupled to the flange, where the latching member includes a retaining feature for releasably coupling the side wall to a lid compatible with the liner. Disclosed fluid containers include a lid having a fluid outlet adapted to couple the lid to the spraying apparatus and a collapsible liner, where either the liner or lid comprises a latch that releasably couples the liner and the lid to each other. Advantageously, the fluid liners and fluid containers can provide enhanced storage options for container contents between spraying operations.

The invention claimed is: 
     
       1. A fluid container for a spraying apparatus comprising:
 a lid having a fluid outlet adapted to couple the lid to the spraying apparatus; 
 a liner that collapses as a fluid contained within the liner is withdrawn from the fluid container; 
 a latch on either the liner or the lid that releasably couples the liner and the lid to each other, the latch comprising a tab that extends across an outer perimeter of the lid; and 
 a rigid outer cup having an open end, 
 wherein neither the lid nor the liner are coupled to the outer cup by the latch. 
 
     
     
       2. The fluid container of  claim 1 , wherein the lid extends over the open end and the liner is received in the outer cup. 
     
     
       3. The fluid container of  claim 2 , further comprising an outer collar releasably coupled to the outer cup, the outer collar securing both the liner and the lid to the outer cup. 
     
     
       4. The fluid container of  claim 1 , wherein the tab comprises a first surface and the lid or liner comprises a second surface opposed to the first surface, wherein the first and second surfaces are releasably coupled to each other. 
     
     
       5. The fluid container of  claim 4 , wherein either the first or second surface comprises one or more receptacles for receiving one or more respective protrusions located on the opposing liner or lid. 
     
     
       6. The fluid container of  claim 4 , wherein either the first or second surface comprises a pressure sensitive adhesive. 
     
     
       7. The fluid container of  claim 4 , wherein the first and second surfaces are coupled to each other by a hook and loop mechanism. 
     
     
       8. The fluid container of  claim 4 , wherein the first and second surfaces are coupled to each other by interlocking microreplicated surfaces. 
     
     
       9. The fluid container of  claim 1 , wherein the latch further comprises a hinge enabling the tab to pivot about the hinge between a first position in which the lid and liner are mutually coupled and a second position in which the lid and liner are not mutually coupled.
